Flu around my daughter?

I was told last night I have the flu (also posted yesterday freaking out because I was so nervous!) I do not have a fever or body aches, but a cough and congestion. I have an 8 year old daughter and my boyfriend has a 4 year old who we had yesterday and tonight into tomorrow. How should I keep from giving the flu to the girls and my boyfriend? I’m so worried!! I am washing my hands, covering my cough, trying to limit my time with them, and washing surfaces. What else can I do? Thank you!

Also, I am 28 weeks pregnant 😩
